Wow thats cool. how did they do it.
Opening file in new tab reviled its. wait what? a png file? this has to be a error.
NOPE!
turns out a file format called APNG animated PNG, allows for animations by extending a normal PNG file past is normal end byte length.
very interesting.
Possible Use cases:
Animated Profiles for websites that disallow .GIF's
Enjoy!
